What a great chip?

[murdoch]

Just got a celeron 800 cdo for 85 bucks canadian retail. Right off the bat set 133 fsb default voltage rock stable. Then i try 140 at 1.85 to be safe and yup. Then 150 at 1.95. 1.2 gigs and I haven't tried lowering it yet. The whole procedure had no lock ups or registry errors once. Temp at 150 is idle 20-23,heavy load 25-29 cel. Using 1 stick of industry standard 512 pc 150 cas 3 (actually a pretested stick of pc 133 cas2).Only paid 54 for it a couple of weeks ago. Using an alpha heatsink with standard fan 5400 rpm. Finally I got lucky.

Good for you! I had a "magic" Cel 266 way back in the day that would do 496 MHz (124 FSB) with stock cooler. Have not had such luck since, but glad to hear you did!

Nice work... and temps. Maybe after she scorches a bit, you can get the voltage nice and low and temps drop more.

What is your ambient temp?

[Bmxpunk86pl]

all i can say is "wow." My 700mhz celly wount even do 1 ghz. at 1.90 volts

Thats crazy overclocking..

Good Job.

Been running at 150 cas 3 for a while. Never tried the jump to 166. Because I wanted to test out this ram first. yup it doesn't do 150 cas 2. It boots and posts fine and works flawless for regular surfing and stuff but I ran prime torture test and got an error after a while so I dropped it back to cas 3 and it ran fine for hours, , figure it will not do 166 at cas 3 then either. Weird thing is that since I started o/c this chip my idle temps have dropped. Its below 20 hovering at 18-19 at 150 fsb at 1.9 volts, heavy loads still gets up to 29 C( dropped voltage a little and runs good will try for the lowest I can fine after I burn it in) If I go back to default at 133 fsb the idle hovers around 14-15. had to drop my temp monitor to 15 for low cpu temp cause it kept going off.Maybe I should have went for the pc 166 ram instead didn't think i could max out this ram with a cel 800. System temp is around 22-23 at idle and 25-27 C at max loads. I am using an abit vh6 2 with an old 250 watt power supply, 486 fan on north bridge and 1 fan blowing in case one out but i am thinking of switching to both blowing out cause with that alpha I want to limit turbulance in this mid tower and their is plenty of ventilation.

man...do you live in an igloo :-)

whats the room temp?

Well I do live in canada. Room temp I am not sure warm enough to wear just a t shirt and no socks if I want.(Yes I am wearing pants except for special occasions.) Its down stairs which is usually cooler in the summer about even in the winter as all the other rooms, I have to say maybe similar to sys temp. But the tower sits closer to the floor. I think I will have to give most credit to the chip,ram and the mighty alpha great cooler.I have a couple of extra sticks of crucial pc 133 cas 2 lying around. Don't use them cause millenium only utilizes 512. So I will pull the 512 chip and stick in the crucial and make some comparisons. I want to go to xp(great drivers, but pretty fluffy to me) so I can use all the ram together but haven't decided over xp or w2k. I am also thinking of pulling the heat sink/fan and see how she does with retail one.If it goes to 133 with reasonable heat, I will recommend this chip as definitley a winner if your looking for one will also post the sspec.

I really like the VH6-II and Celeron 800 cD0 combo, and it sounds like you've taken the right steps. I need to get better ram, scrape the TIM off my HSF, and slap an old cooler on the north bridge. Good chance it'd hit 1200 (8x150) too, but I don't think I'll ever get those same low temps. That's outstanding!

I did a custom build many moons ago, VH6-II and celeron cD0 800 and got 143mhz bus with some kingston RAM and stock cooler. Got temps in the low 40C range under full load, but looped 3dmark2001 for hours and other tests proved to be 100% stable. That's great for 30C case temps and a stock cooler.

I had a P3 cD0 chip that ran relatively cool too... the cD0, next to the Tualatin, was the best coppermine to-date. 1200 is a reasonable goal for these celerons.

One last peice of amazement have got the chip down to 1.75(that was default) at 150 fsb running smooth completely amazed me,just floored me.Followed your advice godfoda you were right on the money. Maybe they are planning on producing a gig hertz cel2 that runs at 133 fsb. Seems to be the only explaination I can find for this chips capability. For those interested here is the sspec for the chip SL5eb. It was retail. I always believed that the lucky guys who got 300a's,533's or p3 700's and p3 1 gig had the best chips for overclocking. A friend has a 700 that does 133 fsb at default voltage. Now I have to add this chip as one of the very best that intel produced for o/c. Of course that was just my experience. Others of course may be different. I don't know if it will continue cause I am converting to xp. I want to use all of the ram I got. I have heard that o/c with more than one stick decreases your chance for succesful o/c,and that xp might not be as allowing as millenium. I will be chucking in a total of 3 sticks.1 512,1 256,and 128.The last 2 are crucial and are cas 2 at 133 but are 7.5 nano as for the 512 is 6.0. I should mention that although running at default voltage(setting it to 1.75 manually in bios) my temp monitor recognizes voltage at 1.80-1.85. Now I know that abit boards run voltage a little high but I thought it was .025 over. So I expected to see it closer to 1.80 but I have seen it as 1.85 in the vhm(205) monitor.Could be the monitor is wrong or it is actually doing it(where as the temp in bios is the same as in the vhm monitor so its a little confusing. I will try another like mbm to verify.I would be using it but it always takes me awhile to setup the right sensor for cpu and system, while the other is dummy proof(perfect for me). I guess I should post these results in the data base. Since I read that its not getting enough attention. Thanks for listening to me

murdoch,

That's some coool running temps you got there.
150% OC ... there oughta be a trophy for that, too (or at least a cold mug-o-draft)

No, that is a 50% oc. It is running at 150% the rated speed.

We've been here before, haven't we ;) ??

I'll leave math to you, I was never good at the simpler items... have me graph something in calculus, I'm all about planes :p

Well, the simple things is what the village idiot(me) is good at :D

lol

I agree, you guess with which part of that statement :cool:

[tainice]

Wow..envy..:eek: i hope my new p700e will do me a 1 gz, then i will be happy...:D not much to ask from it..:p

Max your thinking exactly what I am thinking. I was interested in maybe upgrading this board to the vht so as to take advantage of its use of tualitan chips with out switching teams to amd cause of the cost factor as compared to higher intel chips and chipsets. Along with staying with sdram over buying ddr. The vht was my first choice but i thought it was only allowing a voltage increase up to 1.85. Before I got this cel 800 that bothered me a little cause I think it would cripple my overclocking outside the tualitan. However like you Iam interested whether that 1.85 is strickly for tualitan or does it adjust differently with coppermine chips. If not since its abit and it can go to 1.85 does it still give that extra .025 like the vh2 6. I guess these questions could be answered best by you pinky since you have run both. Thanks it would be appreciated.
